Previous work on pseudomorphic SiGe on Si has shown that a significant reduction in the threading dislocation density can be achieved through appropriate ion beam processing. Helium ion implantation was used in an analogous study to induce strain rel

The growth mechanisms of GaSb in a metal–organic vapor-phase epitaxy (MOVPE) system were studied for both trimethyl gallium (TMG)/trimethyl antimony (TMSb) and triethyl gallium (TEG)/TMSb growth chemistries. The effect of growth temperature and pre

To realize the theoretical advantages of Quantum Dots (QDs) as the active region for diode lasers, the selective growth of QDs on patterned substrates were investigated. The substrate nanopatterning and QD formation was realized by diblock copolymers

Passivation of interfaces corresponding to the nanoposts' sidewalls in InP-based intersubband quantum-box (IQB) lasers has resulted in interfacial-state densities ≪ 1011/cm2. High-quality regrowths of semi-insulating InP around dry-etched, passivat

GaAsSb-GaAsN-based type-II ‘W’ structures have been studied for mid-IR (1.3–1.6µm) emission. Post growth annealing increases the photoluminescence (PL) intensity of the structures. Temperature dependent PL show a charge localization effect due

The conventional approach to fabricate semiconductor based QDs is based on the Stranski-Krastnow (SK) growth mode, which has enjoyed considerable success in device applications. However, the SK QD approach is complicated by the randomness of the QD s
